WebRadix sort is an integer sorting algorithm that sorts data with integer keys by grouping the keys by individual digits that share the same significant position and value (place value). Radix sort uses counting sort as a subroutine to sort an array of numbers. Because integers can be used to represent strings (by hashing the strings to integers), radix sort works on …

WebJan 18, 2024 · So what is Heap sort? Well, heaps are of two type max heap and min heap. The Basic and important rule to follow is that in a max heap the parent node should be greater than that of its child.
